For actually capping flags I use an Assualt shield and KAP 40, put on light weight, scav to restock my non lethals, and extreme conditioning.
If I'm defending the flag I use a Scar with fast mags, and red dot, I use executioner for secondary. Put on Flak Jacket, Tac Mask, and extreme conditioning so I can get in a position to kill someone who has gotten away with the flag. --- I'm the tryhard with the gold ballistics in SnD. Sorry.

I have two specific classes for CTF. One for defending and one for flag running.
Defending class has: SCAR-H, Stock, Quickdraw Flak Jacket, Toughness, Tac Mask + Dexterity (perk 3 greed) C4 + Trophy System
I put the trophy system just out of sight but near the flag, so it stops any grenades going into the flag spot, which is fairly common. I have a C4 on the flag. I run around the flag area and just pop people that come in. As soon as I see the flag is taken I will blow the C4, or if the C4 gets destroyed, then I know they're about to take it.
Very bare bones class, but it can cover a large distance very quickly and you move at 100% speed while ADS. Basically the ultimate run and gun. I use the PDW because of the larger mag size - at the speed you're moving, sometimes reloading is too risky, and I don't have a spare perk for fast mags.
Sometimes I will take off Flak Jacket (heresy!) and put on a Smoke Grenade and a C4 instead. Have experimented with Smokes + Scavenger + MMS as well, works very well but at the cost of a lot of speed based perks. --- PSN: Toastie88 | XBL: Mor7al S7rike | Steam: webbc99 Playing: Final Fantasy VI, Final Fantasy IX, Call of Duty: Black Ops 2, Dark Souls
